Simple API To Get Ethereum Supply And Data

ethereum supply

Recently, there has been debate on Twitter on how to calculate the total supply of Ethereum?

In this article, we will showcase how to use are simple GraphQL APIs to get Ethereum supply and all sorts of other Etheruem blockchain data.

Before moving forward, a word about GraphQL.

GraphQL provides a complete and understandable description of the data in your API, to ask for precisely what data is needed.

Think of GraphQL as writing queries on a database through an API endpoint.

You can query more than 20 blockchains using Bitquery APIs, but today we will only talk about Ethereum.

Bitquery GraphQL endpoint —

Yes, a single endpoint to get all sorts of blockchain data. ?

Ethereum total supply

To get Ethereum’s total supply, run the following query on Bitquery GraphQL IDE.

{ ethereum { transactions { gasValue } transfers(currency: {is: “ETH”}, sender: {is: “0x0000000000000000000000000000000000000000”}) { amount } }}

Here is an example of how to run above the GraphQL query. ?

As you can query result has two values, amount and gasValue. To get total Ethereum supply to subtract gasValue from the amount.

Total Ethereum supply = amount — gasValue

Total pre-mined Eth

More than 72 million ETH were initially pre-mined. To get the exact value of pre-mined ETH, use the following query.

{ ethereum { transfers(currency: {is: “ETH”}, height: {is: 0}, sender: {is: “0x0000000000000000000000000000000000000000”}, receiver: {not: “0x0000000000000000000000000000000000000000”}) { amount } }}

Ethereum pre-mine distribution

To know which addresses got the money in the Ethereum pre-mine, run the query below.

{ ethereum { transfers(currency: {is: “ETH”}, height: {is: 0}, options: {desc: “amount”}, sender: {is: “0x0000000000000000000000000000000000000000”}, receiver: {not: “0x0000000000000000000000000000000000000000”}) { amount receiver { address annotation } } }}

Total ETH sent to the genesis address

To know how many ETH were sent to the Ethereum genesis address, run the following query.

ETH or other tokens sent to genesis address is not recoverable.

{ ethereum { burnt: transfers(currency: {is: “ETH”}, receiver: {is: “0x0000000000000000000000000000000000000000”}) { amount } }}

Large ( > 100 ETH ) transfers to Ethereum genesis address

Run the query below to get the transactions sent to the Ethereum genesis address. The results will be in descending order of the transaction amount.

{ ethereum { transfers(currency: {is: “ETH”}, amount: {gt: 100}, options: {desc: “amount”}, sender: {not: “0x0000000000000000000000000000000000000000”}, receiver: {is: “0x0000000000000000000000000000000000000000”}) { amount transaction { hash } block { height } sender { address annotation } } }}

Total Gas spent on Ethereum.

Ethereum is an EVM, where any execution cost a fee, which is called Gas.

To calculate the total Gas spent on Ethereum, run the query below.

{ ethereum { transactions { gasValue } }}

Total uncle blocks, transaction count and block reward

Uncles are stale blocks that contribute to the security of the main chain but are not considered the canonical “truth” for that particular chain height.

In contrast to orphan blocks (which have no parent), uncle blocks are linked to the chain but are not part of the final selection.

To get total uncle blocks, total transaction count, and total block rewards, run the following query.

{ ethereum { blocks { uncleCount transactionCount reward } }}

Largest Ethereum transfers

Run the following query to get the largest Ethereum transactions. As you can see, the query is filtering transactions where more than 1 million ETH is transferred in a single transaction.

{ ethereum { transfers(currency: {is: “ETH”}, options: {desc: “amount”, limit: 100}, amount: {gt: 1000000}, sender: {not: “0x0000000000000000000000000000000000000000”}, receiver: {not: “0x0000000000000000000000000000000000000000”}) { amount transaction { hash } sender { address annotation } receiver { address annotation } } }}

ETH emission and Gas spent for a given block

If you want to know how many Eth emitted and Gas spent for a given block, run the following query. In this query, we took block number 51 as an example.

{ ethereum { transactions(height: {is: 51}) { gasValue } transfers(height: {is: 51}, currency: {is: “ETH”}, sender: {is: “0x0000000000000000000000000000000000000000”}) { amount } }}

DAO fork transfers

DAO fork created Ethereum and Ethereum classic, therefore, to get the transactions that were included only in Etheruem during the fork, run the query below.

{ ethereum { transfers(height: {is: 1920000}, currency: {is: “ETH”}, options: {desc: “amount”}, receiver: {is: “0xbf4ed7b27f1d666546e30d74d50d173d20bca754”}) { amount sender { address annotation } } }}

Ethereum transactions which used most Gas

Recently, there were two transactions(Tx1, Tx2) that used 10668 ETH Gas to transfer 350 ETH and 0.55 ETH.

Crazy! Right? Most probably, it was a mistake or coding error.

To know the Ethereum transactions that spent the largest gas amount, run the following query.

{ ethereum { transactions(options: {desc: “gasValue”, limit: 10}, gasValue: {gt: 100}) { gasValue sender { address annotation } hash } }}

Get Ethereum token balance in a single API (Including NFTs)

Run the following query with parameters to get all Ethereum token balance in a single call. However, you need to subtract the sum_out from sum_in to get the actual balance.

Balance = sum_in — sum_out


query ($network: EthereumNetwork!, $address: String!) { ethereum(network: $network) { transfers(amount: {gt: 0}, options: {desc: “count_in”}) { sum_in: amount(calculate: sum, receiver: {is: $address}) sum_out: amount(calculate: sum, sender: {is: $address}) count_in: count(receiver: {is: $address}) count_out: count(sender: {is: $address}) currency { symbol } } }}



Get Ethereum balance only

To get only the Ethereum balance of a given address, run the query below.

{ ethereum { address(address: {is: “0x2c82E14352e98c931852D9BB5f0760E36942CC3c”}) { balance } }}

Bitquery Ethereum GraphQL APIs

Using our GraphQL APIs is similar to querying Etheruem blockchain directly.

You can get any data for Ethereum and other blockchains using Bitquery GraphQL APIs.
